Soil-tool interaction of a simple tillage tool in sand

Abstract

This study was focused to experimentally evaluate the draft force on a simple tillage tool operating in different conditions in sand. The soil-tool interaction was evaluated in controlled laboratory conditions in a soil bin. A full multilevel factorial experiment was used with one response variable and four experimental factors. The selected design 3 tools × 3 tillage depth × 3 rake angle × 3 forward speed with two replications had a total of 243 runs. Influence of four independent variables including tillage depth (15, 20, 25 cm), rake angle (25, 35, 50 degrees), forward speed (0.67, 0.98, 1.39 m/s) and cutting-edge angle of the tool (30, 45 and 60 degrees) on draft force as the dependent variable was evaluated.

Design, construction and evaluation of a miniature soil bin plus predicting the measured parameters during primary tests using ANFIS

“…On the other hand, most field studies on tillage tools have been limited by the variable and unpredictable soil nature [ 15 ]. This problem has been overcome primarily by using experimental soil bins where soil-tool interactions can be evaluated in controlled laboratory conditions in a soil bin [ 16 ]. Different types or aspects of soil bin facilities have been developed with varying levels of instrumentation [ [17] , [18] , [19] ].…”

“…The dependence of some parameters of the dynamics of agricultural aggregates on the forward speed has been studied for many decades, with various solutions appearing in many publications (Letosnev, 1959;Moenifa et al, 2014;Cardei et al, 2019;Cardei et al, 2020;Ranjbar et al, 2013;Naderloo et al, 2009;ASAE, 2003 andMcKyes, 1985;Owen 1989;Larson, 1964;Fechete-Tutunaru et al, 2019;Cardei et al, 2023b;Damanauskas, Janulevicius, 2022;Dizaji, 2022;Karmarkar, Gilke, 2021;Askari et al, 2017;Al-Suhaibani, Ghaly, 2010;Elsheika et al, 2021;Deshpande, Shirwal, 2017;Saleh et al, 2021;Rashidi et al, 2013), for example. In general, the draft force depending on the main parameters that define the soil, the geometry of the working bodies, the mass of the machine, the forward speed, the working depth, and the working width was studied and modelled.…”
